Mundo's secret serum

The world known and renown Dr. Mundo, who always saved every patient he had(since they never came back again), one day made a discovery. After various tests, trials and alchemical guesses, he made a new serum that would take over the mind of an individual and they would have to obey every command he would give them. It was almost like a nanobot virus that inhabited the mind of its victim and then listened for his voice to comply with whatever he wanted. It gave him ideas. With so many beautiful women around the world, he decided to set off and live like a king among a harem of girls but first he would have to test in Zaun and Piltover.
